A man suffering from a rare disorder that forces him to vomit up to 10 days a day is hoping a fundraiser will help him access more suitable care. Ryan Lewis, 22, from Sheffield, has been rushed to hospital seven times in the past six months.
Mr Lewis suffers from Cyclical Vomiting Syndrome (CVS). This causes abrupt and repeated attacks - known as episodes - of severe vomiting and waves of nausea.
The duration of episodes varies between a few hours to several days. Although the symptoms of CVS are similar to a stomach infection or bacterial bug, the vomiting episodes are not related.
